推荐答案

如果水印是控件的顶部，那么水印的z顺序是更大而不是对照;这意味着它在控制之后呈现。



更改z顺序，使水印在控件之前呈现。

If the watermark is "on top" of the "control", then the "z-order" of the watermark is "greater" than that of the control; meaning it's rendered "after" the control.

Change the z-orders so the watermark is rendered "before" the control.
